L2TP over IPSec connection problem while IPSec S2S is active on same site

[Tacsko]

Hi Folks!

I have a strange problem.

There are two site, connected with IPSec site to site tunnel. This S2S tunnel has a limited access because of security reasons. Additionaly a few of our users need to connect from same site with L2TP/IPSec VPN personally.
After we moved to OPNSense (from old but quite good IPCop), we cannot connect with L2TP while the S2S tunnel is active. As i've found in firewall log, the L2TP traffic wants to go out in the S2S tunnel, and - i suppose - that's causing the problem.
Has anybody facing with this?
